Product details

Structural characteristics of thermostatic bellows steam traps

 1, the drainage temperature can be adjusted between 70-100 degrees, easy to use. 
 2, to prevent the discharge of high temperature condensate water, to maintain the steam pipeline heat. 
 3, continuous emissions, no noise. Small fluctuations in steam pressure have no effect on use. 
 4, simple structure, easy installation, free. 
 5, by increasing the diameter of the corrugated pipe to increase the amount of condensate arrangement. 
 6, with good emptying performance, not afraid of freezing. Zero leakage, back pressure rate of 75% or more.

Note: 
 1, △ t for the difference between the discharge temperature and saturated condensate temperature, the temperature (△ t) increases, the displacement increases. 
 2, the valve factory hydrophobic temperature has been adjusted at 95 or so, if you want to change the hydrophobic temperature or displacement, the valve can be adjusted to rotate the top of the screw. Turn the spool clockwise to reduce the amount of hydrophobic and reduce the hydrophobic temperature. When the valve is rotated counterclockwise and the spool is retracted, the hydrophobic amount increases and the hydrophobic temperature increases. Tighten the lock nut after adjustment. 
 3, the pressure difference is the pressure difference between the inlet and outlet of the trap, displacement refers to the amount of steam condensate discharged continuously in a unit hour.
